On my machine, the relevent /sys files are located at /sys/bus/usb/devices/usb[1-4]/power/control , the contents of that 'control' file should not be auto for the port that the usb keyboard is plugged in to. Otherwise it will automatically power down after a bit.

I'm using a laptop (ThinkPad x121e). Before today, I always used its internal keyboard and everything was fine. However, today I bought a CM Storm QuickFire Rapid USB keyboard, with which I'm experiencing a problem. The problem is that after being plugged in, the keyboard works OK for some time, then stops working at all. After some replugging, it works again, only to fail again after some more time.Here's the output of dmesg | grep usb:
